Two people have been killed and 14 wounded in a shooting at a nightclub in Norway’s capital Oslo.
People were shot at a number of places in and near the London Pub, a popular gay bar and nightclub in the city centre.
According to public broadcaster NRK, there are at least three crime scenes.
Police said that the suspect was arrested in a nearby street a few minutes later.
The shooter’s motive is not clear.
Journalist Olav Roenneberg, from NRK, said: “I saw a man arrive with a bag, he picked up a gun and started to shoot.”
Oslo is due to hold its annual Pride parade later on Saturday.
